Back Moroccan perhaps to find space (4)
I believe the answer is:
room
'space' is the definition.
(enough space or room to do something)
'back moroccan perhaps' is the wordplay.
'back' is a reversal indicator.
'moroccan perhaps' becomes 'moor' (historical term for a North African Muslim).
'moor' in reverse letter order is 'ROOM'.
'to find' acts as a link.
(Other definitions for room that I've seen before include "Latitude" , "Enclosed indoor space" , "Box ---, storage area" , "bedsit?" , "Space (for elbows?)" .)
